GARBURETER.

Original application filed August 12, 1918, Serial No. 249,534. Dividedand. this application filed Jun 22, 1920. Serial No. 390,740. M r Iuseful Improvements in Carbureters, of

which the following is a specification.

This invention relates to carbureters and particularly carburetersof theconstant level type such as disclosed in my pending application SerialNo. 249,534, filed August 12, 1918, of which this present application isa division.

The objects of the present invention are to provide a float feedmechanism for such a device which shall be certain and reliable inaction, simple and economical in construction and which consists ofrelatively few parts. V

I have illustrated one embodiment of my invention in the accompanyingdrawings, wherein Figure 1 is a vertical section through a carbureterincluding the improved float mechanism. 7

Fig. 2 shows detail horizontal sectional and vertical cross-sectionalviews of the mounting of the float-carrying arm of the float feedmechanism.

Fig. 8 shows in side and edge elevation a supporting bar for thefloat-carrying arm.

Referring to the drawing, wherein similar numerals denote like partsthroughout the several views, the carbureter consists of a lower or bodyportion 1 and an upper portion 2. The carbureter body 1 is formed with afuel chamber 13. This fuel chamber has at one side an extension 65 withwhich it communicates through a vertical slot 66 and said extension isprovided at its lower end with a fuel inlet connection 67. Theconnection 67 terminates in a seat 68 for a fuel valve 69 which isvertically movable in the extension 65, the operation of said valvebeing effected by a lever 70 working through the slot 66 and having aterminal head or ball 71 which is fitted in a recess or slot formed inthe shank of the valve 69. The lever 70 carries a float 72 whichoperates in the chamber 13. In the construction preferred the float 72is in the form of a solid buoyant body, 6. g. cork, and the lever 7 0 isformed with a tapering pointed shank which is driven into the materialof the float and fixed thereto by transverse pins 73. In order to insureof the proper relative posirateneea July 5, rear.

tioning of the lever 70 and the float 72 the lever is provided withsuitably located pro- 1 jections 7 1 preferably formed as punchedouttongues and which, by their engagement against the surface of the float,limit the movement of the pointed shank of the lever into the materialof the float.

The extension 65 and slot 66 extend into the top of the body of thecarbureter and said slot has one of its side walls formed with a lateralrecess 75 which extends from the upper end of the slot to a point somewhat below its lower end. The recess 75 accommodates a vertical bar 76by which the lever is supported, said bar occupying the entire length ofsaid recess and having near its lower end a pin 77 which extends acrossthe slot 66 and provides a supporting pivot for the lever 70. At itsupper end the bar 76 is provided with a lug 7 8.which ex tends acrossthe slot 66 and together with the pin 77 impinges the wall of said slotopposite that in which the recess is formed, thereby to hold said baragainst lateral displacement from said recess, a similar function beingserved by the lower end of the bar which fits into that portion of therecess 75 located below the slot 66.

In the assembling of the carbureter, the lever 70 is fitted to the float72, the bar 76 and the valve 69, after which these parts are placed as aunit in the carbureter, the valve 69 in the extension 65, the float 72in the chamber 18 and the bar 76 in the recess 7 5, said bar thuslocating the pivotal portion of the lever 70 in the slot 66. The bar 76is positively held against upward displacement by the plate and theupper portion 2 of the carburetor or any suitable means associatedtherewith, the upper portion of the fuel chamber, a lever connected tosaid float and to said valve, one of the side walls 01'. said slothaving a recess, and a bar fitted insaid recess and having a pinextending across said slot and upon which said lever is pivoted.

2. A carbureter having a fuel chamber provided with an extension and aslot establishing communication between said chamber and extension, saidextension having a fuel inlet connection terminating in a valve seat, avalve operating in said extension with relation to said seat and havinga recess therein, a float located in said fuel chamber,

a lever connected to said float and having a head engaging the recess insaid valve, one oi the side walls of said slot having a recess, and abar fitted in said recess and having a pin extending across said. slotand upon which said lever is pivoted,

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
